Investigators hold back on releasing cause of death for 22 month-old boy left in car

Cobb County investigators said it will likely be next week before the cause of death can be released in the case of Cooper Harris, the 22 month-old boy found dead by his father, Justin Ross Harris, in the backseat of his car Wednesday evening. Police said Harris had his son with him on his way to work Wednesday, but accidentally left the boy in the backseat all day.

However, Sgt. Dana Pierce said Friday that the information currently known to the public in this case is "just the tip of the iceberg," and that other pertinent details are likely to not be released by investigators until the case goes to trial.

Pierce also confirmed that investigators served search warrants at a Home Depot facility near Akers Mill, where Harris worked Wednesday morning and afternoon before discovering his son dead. Pierce said the cause of death has not yet been released because the Medical Examiner and investigators are still working to confirm all aspects of the case.

Harris, 34, was denied bond by a judge Thursday night. He remains in the Cobb County jail until his next hearing, scheduled for mid-July.
